Detailed explanation of rear bar inner frame support.
First, the definition and function of the skeleton support in the rear bar
The rear bar internal frame bracket, referred to as the rear bar bracket, is an automotive structural component used to support the rear of the body and connect the wheels to the body. Its essence is a bearing structure that guarantees body stability and safety by transmitting the force from the rear of the car to the wheels, body and chassis.
In automotive design, the rear bar bracket usually has the following functions:
1. Support the rear of the body to avoid the collapse of the tail and ensure stability during driving.
2. Resist the impact of vehicle collision and reduce accident damage.
3. Connect the wheel and the body, coordinate the movement of the body and the wheel, and make them match each other.
Second, the difference between the rear bar bracket and the traditional skeleton bracket
There are some differences between the rear bar bracket and the traditional frame bracket. A kind of traditional skeleton bracket is welded by the body steel plate, and the rear bar bracket pays more attention to lightweight and high strength, so it is made of aluminum alloy, titanium alloy, composite materials and other materials to reduce the weight of the vehicle and improve the body stiffness.
The advantage of this is that the bending strength and twisting strength can be improved without affecting the stability and hardness of the vehicle, so that the vehicle has better handling and safety.
Third, the application field of the rear bar bracket
Rear bar bracket is generally used in car, SUV, MPV and other vehicle production. In addition to the conventional material selection and manufacturing process, the rear bar bracket also needs to choose different installation methods according to different models.
For example, for modern cars, the rear bar bracket needs to adopt a tailgate type design to meet the aesthetic and safety requirements of the vehicle. For vehicles such as SUVs, the rear bar bracket is usually designed in a triangle or T shape to ensure traction safety and load capacity.
Four, rear bar support maintenance and precautions
In order to ensure the service life and performance of the rear bar bracket, we need to do the following things during use:
1. Avoid over-hauling the vehicle when starting and accelerating, so as not to produce excessive load.
2. Keep the vehicle surface clean to avoid friction and wear with debris.
3. Regularly check the fasteners and welds of the rear bar support to ensure their safety and reliability.
To sum up, the rear bar frame is a very important structural component in the car, its function is mainly to bear the load of the rear of the vehicle and connect the body and the wheel. In practical applications, we need to choose the right material and design according to different models and use environments to ensure the function and safety of the rear bar bracket.

1, the first is to install the side pedal. Get tools -- sleeves, adjustable wrenches, flat wrenches, ratchets, Phillips screwdrivers, and a flashlight.
2, lie down the car to find the support installation hole two holes, in the original car is blocked by two rubber things to install T-bolts, because the inside of the surface is a little lower, so to pad a pad.
3, install the rear bracket, the rear bracket installation need to remove the bolt of the original car, and then install a longer bolt card main bracket.

6, install the bracket, the accessory force is to use self-tapping screws, I suggest that you use bolts to connect more reliable and then install the bracket will remove the two holes of the buckle to install the upper and lower brackets. Wrap the front bars with sponge. Put the front bars in.
7, screw on the bracket nut, it is recommended to use the self-locking nut to screw off the gap and plate after the bracket bolt is installed, install the rear bar, first install the stud on the rear bar, than in the original car, do a good mark and drill holes.
